Steady-eyed like her husband, she preserved an air of unfathomable indifference behind the rampart of the counter.

Then the customer of comparatively tender years would get suddenly disconcerted at having to deal with a woman, and with rage in his heart would proffer a request for a bottle of marking ink, retail value sixpence (price in Verloc's shop one-and-sixpence), which, once outside, he would drop stealthily into the gutter.
The evening visitors--the men with collars turned up and soft hats rammed down--nodded familiarly to Mrs Verloc, and with a muttered greeting, lifted up the flap at the end of the counter in order to pass into the back parlour, which gave access to a passage and to a steep flight of stairs.

The door of the shop was the only means of entrance to the house in which Mr Verloc carried on his business of a seller of shady wares, exercised his vocation of a protector of society, and cultivated his domestic virtues.

These last were pronounced.

He was thoroughly domesticated.
